Description

  The present invention relates to a sealing seal and a method of using the sealing seal, and more particularly, when a sealed bag or box is opened by an unauthorized third party, the trace remains, and when the bag or box is opened by a legitimate party, the first opening is performed. The present invention relates to a sealing seal that can be clearly recognized as a person and a method of using the same.

  A pressure-sensitive adhesive layer for adhering to an object to be sealed (hereinafter also referred to as an adherend) is formed on the sealing seal, and usually between the base material of the sealing seal and the pressure-sensitive adhesive layer, It has a special structure to leave a trace when it is opened. For example, a release layer, a metal vapor deposition layer, and a pressure-sensitive adhesive layer are sequentially formed on one side of the base material, and the pressure-sensitive adhesive layer is protected with a release paper. When affixed and the sealing seal is peeled off from the adherend, the structure peels off at the boundary between the release layer and the metal vapor deposition layer.

Since the sealing seal once peeled off at the boundary between the peeling layer and the metal vapor deposition layer cannot be attached again, it functions to leave a trace when opened.
In addition, there is a sealing seal using an easily breakable structure (see, for example, Patent Document 1).
This makes it known that fraud has been performed by leaving a residue of a specific shape on the adherend when the sealing layer is made into a pattern and the base material of the seal is peeled off.
Such sealing seals are used for sealing foods, cosmetics, software for personal computers, genuine parts for export, and the like.
In addition, the sealing sticker can be seen to have been opened, and when the sealing target is intended for an individual consumer, especially when used for cosmetics, it must be beautiful in appearance. Is also an important factor.
